Control method and system for improving curled edge loss caused by wave shape of finish-rolled strip steel

The invention relates to a control method and system for improving a curled edge loss caused by the wave shape of finish-rolled strip steel. According to the control method, an additional value set value of the opening of a curled side guide plate is adjusted in real time according to a straightness detection value of the wave shape of the finish-rolled outlet strip steel, accordingly a control technology of the curled edge loss is improved, and the problems that in the prior art, the curled edge portion damage of hot-rolled strip steel is mainly improved through curled side guide plate position control, curling tension control and the like, and the improvement is limited; and due to manual intervention, the information transmission delay and lag are caused, it is too late for the side guide plate to act, and the strip steel edge loss defect caused by the wave shape is difficult to avoid and reduce effectively are solved. 本发明涉及种改善带钢精轧浪形引起卷取边损的控制方法及系统，本发明是根据精轧出口带钢浪形平直度检测值，实时调整卷取侧导板开度附加值设定值，进而改善卷取边损的控制技术，解决现有技术
